Cataclysm Beta - Build 12479
A new build of the beta is up. This post will be updated multiple times during the night.

A lot of stuff has changed and we'll need a few mins to fix everything before I can post all the content. Definitely a lot of interesting stuff, stay tuned.

Talent CalculatorWoWTal.com has been updated with all the new trees. Lot of stuff is still in dev, be careful. If you can't see the new trees push CTRL + F5 to force the refresh (Also, I know the level cap is 50, quick hack to fix the max amount of points)

Classes
Classes pages are up. I might end up doing diffs of all the changes but seriously ... there are really a LOT of changes because of the talent trees revamp, it's probably easier to just check the pages.

Guys;
[blizzquote="Ghostcrawler;http://forums.worldofwarcraft.com/thread.html?topicId=25968669894&pageNo=1#3]We are going to turn both Holy Shield and Shield Block into short cooldowns. A short cooldown is an ability that you don't save for an absolute emergency (like Shield Wall) but we also don't want it to be on such a short cooldown that it feels maintenance-y. It's a tricky number to get right, but something in the 30 sec to 1 min zone feels about right. Then you might use Holy Shield one GCD instead of SoR or you can choose to save it until the next big boss attack.[/blizzquote"]

And another;

Buckle up. Tonight's going to be a wild ride with all the new talent info out.

I find it interesting to note that those two unused zones in lower Eastern Kingdoms (between Elwynn and Dun Morogh, and between Badlands and Redridge), plus that little unused eastern hook of Redridge seem to have fallen into the ocean. Not just they've been appropriated into other zones (except a tiny bit of that western one seems to have been absorbed into Elwynn), but they've just disappeared. Yet despite this, the unused zone north of the Plaguelands is still there. Intriguing.

All those unused zones were placeholder zones as far as I know. I'm not surprised that they decided to dump most of them. The zone north of the Plaguelands is very interesting though..

what on gods green earth is all this breadcrumbs stuff about? its making me hungry

It's like 1 quest you get in a city that sends to you some place that will have a whole bunch of quests for you, its a sort of bread crumb trail to the questing areas, EX. i hear so and so needs help in XXX zone go help them or EX2. I haven't heard back from XXX in a while, he was last known is XXX go see if you can find out what happened. They will be in the capital cites like Stormwind/Orgrimmar that send you out to zones of your appropriate level.
